Chapter 1. Overview Of Base Station
1.3.1.1 DHCP Server and IP Address Assignment
The PacketMax System supports Dynamic Host Configuration Protocol (DHCP),
which manages IP address assignment for most interfaces in the PacketMax devices.
NOTE:
In the configuration of the DHCP server, the PacketMax System IP
addresses must be fixed—i.e., reserved for the specific units; they cannot
currently be dynamically assigned, but this planned for a future software
release.
Specifically, PacketMax System IP addresses are assigned as follows:
The BS receives the IP address of its backhaul interface from the DHCP server
for its subnet.
The BS’s wireless interfaces (WSC) are assigned IP addresses as part of the
BS configuration (using the WaveCenter Configuration Manager).
SS receive the IP addresses of their wireless interfaces from the DHCP server.
Computers, PCs and other hosts that WaveCenter EMS configures for its
DHCP server, connected to he SS receive IP addresses in a variety of ways:
-
From ISP’s DHCP server, via DHCP relay agents in the SS.
-
By manual assignment by the ISP.
1.3.2 Services
Each Base Station Unit requires access to DHCP and TFTP servers to boot up prop-
erly. Access to additional servers is required for the support of specific features.
1.3.2.2 TFTP Server
For the PacketMax System, the main function of the TFTP server is to store the
system configuration files, and download them on request. Each Base Station Unit
and Subscriber Unit requests its configuration file on hardware or software reboot
(cold or warm start). A TFTP Server is included in EMS.
NOTE:
Whenever a Base Station Unit or Subscriber Unit boots up, the con-
figuration file must be successfully downloaded from the TFTP server for the
unit to become operational. If the configuration file is not successfully down-
loaded, the BS or SS will come up in standby mode.
1.3.2.3 SNTP Server
The Base Station Unit typically derives the time and date from an SNTP (Simple
Network Time Protocol) server identified by the DHCP server. The BS includes time
zone and daylight savings time parameters which it applies to the received time and
date as appropriate. A SNTP Server is not included in EMS.
NOTE:
Alternatively, date and time can be set via the Web and SNMP inter-
faces.
Subscriber Units use the BS as their time server.
